    lexer: Fix use-after-free error in lex_source_get_lookahead().
    
    This code used local variable 'out' as if its value stayed the same from
    one iteration of the loop to the next, but in fact its scope meant that
    it became indeterminate on each new iteration.  This commit fixes the
    problem by moving its declaration to an outer scope.
    
    Thanks to John Darrington for reporting the problem.
